Network & Communication

The ComNet FDX60(M,S)[-M] data transceivers provide point-to-point transmission of simplex or duplex EIA RS232/RS422/RS485 (2W/4W) data signals over one or two optical fibers. The transceivers are transparent to data encoding allowing for broad-range compatibility. Models within this series are available for use with multimode or single mode optical fiber.

Features for FDX60 Series

• Robust design assures extremely high reliability in unconditioned out-of-plant/roadside environments
• NTCIP compatible
• Wide optical dynamic range: optical attenuators are never required
• Status indicating LEDs provide rapid indication of critical operating parameters.
• Meets EIA RS232C/D and RS422/RS485 (2 or 4-wire) specifications
• Fiberlink Fiber Link Tester
• Voltage transient protection on all power and signal input/output lines provides protection from power surges and other voltage transient events.
• Tested and certified by an independent laboratory for full compliance with the environmental requirements (ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/low-line voltage conditions and transient voltage protection) of NEMA TS-1/ TS-2 and the Caltrans Specification for Traffic Signal Control Equipment.
• Standard ComFit models are hot-swappable.
• Lifetime Warranty
• ComFit standard form factor is designed for wall, surface, rack, or DIN rail mount installations (using optional card cage or DIN mounting bracket).
• Compact form-factor saves space in those installations where space may be at a premium.

The ComNet™ FDX72(M,S)1 series Drop-Insert-Repeat Transceiver unit is a fullydigital modem designed for implementing RS232, RS422 or RS485 2 or 4-wire data communications networks of the highest possible reliability. A network of FDX72 units can support one full-duplex or two half-duplex data channels. These transceivers also feature data translation to convert between data protocols. Data re-clocking and regeneration permit an almost unlimited number of transceiver/controller units to be used within the network. These environmentally hardened transceivers are ideal for use in unconditioned out-of-plant or roadside installations and, unlike many competing designs, only one optical fiber is required between units. Combine these units with the ComNet FDX70E(A,B)(M,S)1 series products as an end link to create a linear Drop-Insert-Repeat chain. Plug-and-play design ensures ease of installation, and no electrical or optical adjustments are ever required.

The ComNet FDXT1/E1 data transceivers are T1/E1 links that support AMI and B8ZS data signals over one single mode or multimode optical fiber. The transceivers synchronize and regenerate data to eliminate jitter accumulated through the link. Models within this series are available for use with multimode or single mode optical fiber. Plug-and-play design ensures ease of installation requiring no electrical or optical adjustments. Each transceiver incorporates a bi-color (Red/Green) indicating LED for monitoring proper system operation. The FDXT1/E1 standard size units may be either wall or rack-mounted in a ComNet card cage, or may be installed in an IFS R3 rack with the selection of the corresponding model.

Features

• Robust design assures extremely high reliability in unconditioned out-of-plant/roadside environments
• Status indicating LEDs provide rapid indication of critical operating parameters.
• Remote Fault Indication allows the user to determine when a fiber break or loss of prime operating power has occurred, or a transceiver in the field has failed
• Wide optical dynamic range: optical attenuators are never required
• Designed for installation in harsh out-of-plant/unconditioned industrial or roadside operating environments (-40? to +70?C ambient). Fully compliant with the environmental requirements of NEMA TS-1/TS-2 for Traffic Signal Control Equipment
• Lifetime Warranty
• Fit and Functional Replacement for IFS D1200-R3 Series
• Single Fiber Design
• Voltage transient protection on all power and signal input/output lines provides protection from power surges and other voltage transient events.
• ComFit standard form factor is interchangeable between stand-alone or rack mount use.
• Standard ComFit models are hot-swappable.

The ComNet™ FTA/FRA2C1 Series audio multiplexer provides the transmission of two audio signals and one contact closure over one multimode or single mode optical fiber. A bidirectional model, FXA2C1(M,S)1, is also available. The modules use 24-bit 96kHz sample rate digital encoding for superior transmission of balanced line-level audio. Plugand-play design ensures ease of installation and no electrical or optical adjustments are required. Bi-color LED indicators confirm operational status. Packaged in the exclusive ComNet ComFit housing, these units may be either wall or rack mounted.
